Application flled February 12, 1928. Serial 110,618,501. i I

To all whom it may concern:

Be it known that I, EDWARD a citizen of the United States, residing at San Leandro, in the county of Alameda and State of California, have invented certain new and useful Improvements in Bolts, of

- which the following is a specification.

This invention relates in general to bolts for fastening purposes, and 1n particular to bolts for securing the demountable tirecarrying rim to an automobile wheel;

The objects of the invention are to facilitate the use of such a bolt; to-prevent its being pushed out of position-in assembling the parts to be connected thereby; to prevent the turningof the body of the bolt in' tightening and loosening the nut; and such other purposes to which the bolt may be applicable.

In carrying out my invention, I construct the bolt with a laterally projectin lug upon one side thereof in proximity to the head of the bolt, with a predetermined space between lug. The lug is preferably, in cross-section, substantially of the "shape of an isosceles triangle, the body of the bolt being the base of the triangle.

My bolt is of special utility in securing demountable tire-carrying rims to automobile wheels, and]: will now escribe it with reference to such use. Other uses of the bolt will be readily apparent and suggest themselves to the mechanic from such description.

In ithe accompanying sheet of drawings, have illustrated my bolt and its use in con'v' nection with an automobile wheel.

Fi ure 1 is a side-elevation of the lug and the head of the bolt, the nut being omitted. I

Fi ure 2 is a cross-section of the bolt along the .line AA of Fig. 1, looking in the direction of the arrows.

Figure 3 is a cross-s ection of a portion of an automobile wheel, showing a tire and a I the bolt-i i showing the lateral lug and the space between;

and secured.

Referring to the drawing an'd' the" figures thereof..:''The automobile wheel represented" g f by thejnumeral 1, is rovi cledwit-h thetusual l0 felloe 2, uponwhic 1; is supported the demountable rim 3,, carrying the tire The; rim 3 rests directly upon the supporting flange 5 of the felloev on the-innerside oi I theflwheel, and indirectlyupon messag s on-theouter side .ofthe wheel.

is a wedge member, interposed'between I the" flange 6 and the rim; 3f, sei'ving,tocenter the rim 3 upon the fe-lloe. 1e wedgefm'em- I hers, offwhich there in aybe' any desired inum her, are .providedw'ith ears amendin -m ward the, center of they wheel for engaging the boltsl The tendency at the present time is to make the members 7 integral with the rim,3, thereby increasing the need of abolt capable of preventing-its rotation and at Lthe same time preventing its longitudinal the said head and the adjacent end of the j get er. I"

dis laceme-nt when the parts are securedjtoslipped on them and into place, that the bolts 88 in most instances were pushed back'and out ofengagement, and that the operator then had "to reach between the wheel spokes or. 4 around the tire to replace the bolts in osi- .tio n'oif hold them there ,'with the risr of 90 -srnearin g or soiling his clothes. f

v f With"1 3?ibolt's,9;there-isv no such casualt possible, becauseathebolt is "provided w-it alateral lu .11 ,iadapted ;to [pass through a correspon ingly shapedhole 14 (Fig. 4) 5 in the flange 5 thereof. "After insertion the bolt is partially rotated and the flange 5 is thereby engaged between the lug 11 and the head 13 of the bolt, in the space 12 between those parts. Thus the bolt is firmly held aagainst longitudinal movement with res ect to flange 5. The demountable rim may t en be slipped on with the ears-'8encirclingthe bolts, and the nuts put on and tightened. The tightening 9 to. turn un the-lugs 11 contactjle base of the felloe mem-bcrias at 10, fFi-g, and

the bolt is thereby held against further rotation. In loosening the nuts, the bolts turn in the opposite direction until the lugs-11 1-10 of the nuts cause. the bolts contact the base on the other side, as shown in dotted lines also in Fi invention, therefore, what I claim as new 4:. In cases where there is%)ut a narrow margln between the bolt hole and the edge of the felloe as seen at 15in Fig. 3, the bolt head may be flattened as at 16 in Fig. 2, so that when the bolt is in its final holdin position, the flattened portion of the hea vwill re ister at the edge of the rounded portion 0? the felloe, thus presenting a neat ap earance. 1

While I have thus described the preferred form of my invention, I wish to have it un- 1 derstood that slight changes may be made 15 within the scope of the claims hereto attaehed Without afi'ecting the spirit of the and desire to secure by patent protection thereon in the United States, is the follow mg: a 4

1. In combination with a supporting flange provided with an opening therethrough, a straight bolt consisting of a head and a round body and having on the latter a triangular-shaped projecting lug spaced from said head a distance substantially equal 2. A bolt, comprising a head and body, the

body thereof provided with a lateral lug spaced from the head a predetermined distance, a support therefor having an opening of the size and shape of the cross-section through the body and lug, the lug adapted to be turned out of registry with the said opening in said support after insertion, the

said lug preventing the bolt from being backed out of engagement with said support, and said lug iurther adapted to engage the base of the support to prevent rotation of the bolt.
